These data files include the base data files, which contain tables, indexes, and data of other objects in the database. Reading data from data files can become a bottleneck in the performance of the database, especially when the database is large and experiences a high volume of concurrent queries. Optimizing PostgreSQL Data File Read is essential to improve the performance of the database system and minimize the response time of queries. https://www.toidang.xyz/posts/2022/08/07/master-master-vs.-master-slave-replication-in-distributed-relational-databases/ Sun, 07 Aug 2022 18:08:55 +0700 https://www.toidang.xyz/posts/2022/08/07/master-master-vs.-master-slave-replication-in-distributed-relational-databases/ In the distributed relational database model, two common modules are master-master and master-slave replication.
